I notice that when loaded, my AI hull does not sit on the stern cradle. Instead, the Amas sit on the cradle and hold the main hull about 3/4 inch up above the cradle. Therefore, the majority of the boat's weight is being carried by the Ama cross braces.

This doesn't seem right but I've adjusted quite a bit and is as close as I can get things.

I can take some but there's not much to see - the boat hull is up off the cradles.

I have them about 67 inches apart - slid them up and back to get the most conforming fit. The front is settled nice and trim with the forward cradle sitting just under the forward half of the mirage drive well. Nice fit between cradle and hull there.

67.5 inches to the rear (measured center to center) the rear of the hull fits perfectly until you fold the Amas in and place then in the cradle. Then they lift the rear of the boat off the cradle.

I've built quite a few trailers so I could do that if I had to. My preference is to trailer the boat mostly assembled with the Amas in place. Most likely I'll just shim the center of the cradle to fit this boat in such a way that the hull will be supported from below rather than hanging from the Amas.

The akas tend to rotate in the crossbar receivers when the akas are folded back, causing the amas to sag when the boat is out of the water (terrible bloody design ). This is also what causes the akas to become jammed in the crossbars. This may be what is making the boat rest on the amas, instead of the hull.

Here's a shot of the under-carriage, so to speak. You can see the Amas are bottomed out in the cradle but none of the hull is supported by the cradle. Note the 3/4 inch space between the hull and cradle. The hull is hanging by the Ama attached crossbar.

Here is a shot of where I have the stern cradle located (If you wonder why the trailer is on blocks instead of wheels and tires - the dealer forget to send them. But this has no effect on the cradle or hull).

Sliding the hull forwards or backwards a bit does not change anything. This is as close as I can get it.

Tom - try this easy fix.Once you have loaded the AI onto the trailer complete, just release the bungies that secure the amas to the akas.I never connect them until I am about to launch.Releasing the tension will enable the akas to pop up slightly and ensure that the hull is supported by the cradle.

It may be just parallax, but looking at the side-on photo, the starboard aka seems to be at a lower angle than the port one. Looking at the underneath photo, the boat seems to be resting on the starboard ama only. Can you force the starboard aka slightly so that it rotates upward in the crossbar?

I removed the bungees and nothing changed. There is about 1/8-inch space between the Amas and the hull. The photo may not be clear enough to show that tiny bit of space, but the two are not in contact.

The cradles are pulling the Amas in just snug to the hull. If I slide the boat (or the cradle) fore or aft, everything gets worse.
